http://www.cs.wisc.edu/condor/ Condor <title_line>distributed resource management system for large heterogeneous clusters of workstations <abstract> Condor is a distributed resource management system that can manage large heterogeneous clusters of workstations. Its design has been motivated by the needs of users who would like to use the unutilized capacity of such clusters for their long-running, computation-intensive jobs. Condor has been ported to most UNIX platforms and has been used in production mode for more than 8 years in our department and a wide range of other sites. Condor pays special attention to the needs of the interactive user of the workstation. It is the interactive user who defines the conditions under which the workstation can be allocated by Condor to a batch user. Condor preserves a large measure of the originating machine's environment on the execution machine, even if the originating and execution machines do not share a common file and/or password systems. Condor jobs that consist of a single process are automatically checkpointed and migrated between workstations as needed to ensure eventual completion. <contact>condor@cs.wisc.edu <environment>http://www.cs.wisc.edu/condor/platform.html <category>misc </urc>
